That you can't always look at a single metric as a basis for success? This is rudimentary analytics here. Is there a single person who believes making client side code heavy is the way to go? Do people really think user experience should take a back seat to cool stuff on a site like YouTube?
Try "what makes a site merely inconvenient for some can render it completely unusable for others, and so one should not overlook minor issues because they don't seem worth fixing."
